How can one add a user-defined property library in HYSYS?
Looking for a hero! Top first! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
I don’t understand what you mean. HYSYS allows the addition of virtual components; you just need to enter the physical properties of your substance
This one is quite troublesome. . One needs to write the code themselves. . The workload is very large
I’ve encountered similar problems too. How exactly is it done? Are there any help documents or something? It would be best to have one that can perform table interpolation. Also, a reply to the 3rd floor. For virtual components, calculations are still done using formulas, but in the range of physical properties I am working with, the values obtained from these formulas are inaccurate, which has a significant impact.
This software comes with a PDF file that provides detailed information; it’s called AspenHYSYSV7_2-Cust.pdf. That file contains thorough explanations as well as the relevant code. Hey, you can study it on your own – I haven’t studied it yet
The results calculated using virtual components are still usable; however, the default method used needs to be changed. Once that is done, the calculation results will be accurate, otherwise the errors will be quite large
Interfaces do exist, but they are not open.
The VBA interface can be used to calculate the property tables for virtual components, and then assign those values to the corresponding properties; batch processing thus turns them into a database. Hehe
After obtaining the physical properties of each component, they can be exported as a cml file.
